PAM降解后的影响

•  对环境的影响:

•  PAM（聚丙烯酰胺）在自然环境中难以生物降解，其降解速度较慢[⁠⁣ ⁠⁣](https://baijiahao.baidu.com/s?id=1778267704932542874)[4](https://baijiahao.baidu.com/s?id=1778267704932542874) 。这可能导致PAM在环境中的积累，进而对生态系统产生潜在威胁。

•  降解后的单体丙烯酰胺对人类的神经系统有较大的危害[⁠⁣ ⁠⁣](https://m.zhangqiaokeyan.com/academic-journal-cn_journal-agro-environment-science_thesis/0201281754411.html)[7](https://m.zhangqiaokeyan.com/academic-journal-cn_journal-agro-environment-science_thesis/0201281754411.html)[⁠⁣ ⁠⁣](https://wap.cnki.net/touch/web/Journal/Article/YQTB200504014.html)[15](https://wap.cnki.net/touch/web/Journal/Article/YQTB200504014.html) 。

•  对水质的影响:

•  PAM降解过程中可能释放小分子有机/无机碳化合物[⁠⁣ ⁠⁣](https://xueshu.baidu.com/usercenter/paper/show?paperid=efc871aef6789eeb9309a81433ce8cea)[11](https://xueshu.baidu.com/usercenter/paper/show?paperid=efc871aef6789eeb9309a81433ce8cea) ，这些化合物可能会影响水体的化学需氧量（COD）和生化需氧量（BOD），从而减缓水体中有机质的降解速度，降低反污染效果[⁠⁣ ⁠⁣](https://baijiahao.baidu.com/s?id=1810160226554176886)[8](https://baijiahao.baidu.com/s?id=1810160226554176886)[⁠⁣ ⁠⁣](https://m.baidu.com/from=1036777e/bd_page_type=1/ssid=0/uid=0/pu=usm%400%2Csz%401320_220%2Cta%40iphone___24_69.0/baiduid=C07F0FD1710C2C904376517A0A6178C5/w=0_10_/t=iphone/l=1/tc?ref=www_iphone&lid=9955840558256928130&order=1&fm=alop&isAtom=1&clk_info=%7B%22tplname%22%3A%22lego_tpl%7C13237%22%2C%22srcid%22%3A1529%2C%22jumpType%22%3A%22%22%2C%22urlsign%22%3A%2212301703695202584077%22%7D&is_baidu=0&dict=-1&tj=lego_tpl_1_0_10_l1&wd=&eqid=8a2a403d4b54b58210000002662543eb&w_qd=IlPT2AEptyoA_yimJVOcUTc5xg0WLOukJxuZQGBX0TPuzJjpqK_wVAEqEmKgBC44VZGbd_&bdver=2_1&tcplug=1&sec=38032&di=0d2125bb14dc03e4&bdenc=1&nsrc=bE1eyj%2FPZdJHimi%2BXbg4vJ8mfpSyshW3mEkarqlPRFOr%2FQJFZBiQkGw%2BKQEK0PtLjUcl3Hqvlu4%2BILV5Eh%2BOmmU6d0RYA%2BN%2Br3PgdKxRJUHAeEBMgOAc5s%2FxH99FAqzI)[14](https://m.baidu.com/from=1036777e/bd_page_type=1/ssid=0/uid=0/pu=usm%400%2Csz%401320_220%2Cta%40iphone___24_69.0/baiduid=C07F0FD1710C2C904376517A0A6178C5/w=0_10_/t=iphone/l=1/tc?ref=www_iphone&lid=9955840558256928130&order=1&fm=alop&isAtom=1&clk_info=%7B%22tplname%22%3A%22lego_tpl%7C13237%22%2C%22srcid%22%3A1529%2C%22jumpType%22%3A%22%22%2C%22urlsign%22%3A%2212301703695202584077%22%7D&is_baidu=0&dict=-1&tj=lego_tpl_1_0_10_l1&wd=&eqid=8a2a403d4b54b58210000002662543eb&w_qd=IlPT2AEptyoA_yimJVOcUTc5xg0WLOukJxuZQGBX0TPuzJjpqK_wVAEqEmKgBC44VZGbd_&bdver=2_1&tcplug=1&sec=38032&di=0d2125bb14dc03e4&bdenc=1&nsrc=bE1eyj%2FPZdJHimi%2BXbg4vJ8mfpSyshW3mEkarqlPRFOr%2FQJFZBiQkGw%2BKQEK0PtLjUcl3Hqvlu4%2BILV5Eh%2BOmmU6d0RYA%2BN%2Br3PgdKxRJUHAeEBMgOAc5s%2FxH99FAqzI) 。

•  过多的PAM使用还可能导致水体变得黏稠，影响水的透明度和视觉效果[⁠⁣ ⁠⁣](https://www.hbzhan.com/tech_news/detail/1347593.html)[5](https://www.hbzhan.com/tech_news/detail/1347593.html)[⁠⁣ ⁠⁣](https://m.baidu.com/from=1036777e/bd_page_type=1/ssid=0/uid=0/pu=usm%400%2Csz%401320_220%2Cta%40iphone___24_69.0/baiduid=C07F0FD1710C2C904376517A0A6178C5/w=0_10_/t=iphone/l=1/tc?ref=www_iphone&lid=9955840558256928130&order=1&fm=alop&isAtom=1&clk_info=%7B%22tplname%22%3A%22lego_tpl%7C13237%22%2C%22srcid%22%3A1529%2C%22jumpType%22%3A%22%22%2C%22urlsign%22%3A%2212301703695202584077%22%7D&is_baidu=0&dict=-1&tj=lego_tpl_1_0_10_l1&wd=&eqid=8a2a403d4b54b58210000002662543eb&w_qd=IlPT2AEptyoA_yimJVOcUTc5xg0WLOukJxuZQGBX0TPuzJjpqK_wVAEqEmKgBC44VZGbd_&bdver=2_1&tcplug=1&sec=38032&di=0d2125bb14dc03e4&bdenc=1&nsrc=bE1eyj%2FPZdJHimi%2BXbg4vJ8mfpSyshW3mEkarqlPRFOr%2FQJFZBiQkGw%2BKQEK0PtLjUcl3Hqvlu4%2BILV5Eh%2BOmmU6d0RYA%2BN%2Br3PgdKxRJUHAeEBMgOAc5s%2FxH99FAqzI)[14](https://m.baidu.com/from=1036777e/bd_page_type=1/ssid=0/uid=0/pu=usm%400%2Csz%401320_220%2Cta%40iphone___24_69.0/baiduid=C07F0FD1710C2C904376517A0A6178C5/w=0_10_/t=iphone/l=1/tc?ref=www_iphone&lid=9955840558256928130&order=1&fm=alop&isAtom=1&clk_info=%7B%22tplname%22%3A%22lego_tpl%7C13237%22%2C%22srcid%22%3A1529%2C%22jumpType%22%3A%22%22%2C%22urlsign%22%3A%2212301703695202584077%22%7D&is_baidu=0&dict=-1&tj=lego_tpl_1_0_10_l1&wd=&eqid=8a2a403d4b54b58210000002662543eb&w_qd=IlPT2AEptyoA_yimJVOcUTc5xg0WLOukJxuZQGBX0TPuzJjpqK_wVAEqEmKgBC44VZGbd_&bdver=2_1&tcplug=1&sec=38032&di=0d2125bb14dc03e4&bdenc=1&nsrc=bE1eyj%2FPZdJHimi%2BXbg4vJ8mfpSyshW3mEkarqlPRFOr%2FQJFZBiQkGw%2BKQEK0PtLjUcl3Hqvlu4%2BILV5Eh%2BOmmU6d0RYA%2BN%2Br3PgdKxRJUHAeEBMgOAc5s%2FxH99FAqzI) 。

•  对微生物的影响:

•  高浓度的PAM可能会抑制微生物的活性，影响水中微生物的生长，导致水体异味等问题[⁠⁣ ⁠⁣](https://baijiahao.baidu.com/s?id=1811070100577053284)[10](https://baijiahao.baidu.com/s?id=1811070100577053284)[⁠⁣ ⁠⁣](https://baijiahao.baidu.com/s?id=1778266772164306780)[17](https://baijiahao.baidu.com/s?id=1778266772164306780) 。

•  某些微生物在特定条件下可以降解PAM，但这一过程相对缓慢，且效率受多种因素影响[⁠⁣ ⁠⁣](https://m.doczj.com/doc/0e22305452.html)[3](https://m.doczj.com/doc/0e22305452.html)[⁠⁣ ⁠⁣](https://m.zhangqiaokeyan.com/academic-journal-cn_journal-agro-environment-science_thesis/0201281754411.html)[7](https://m.zhangqiaokeyan.com/academic-journal-cn_journal-agro-environment-science_thesis/0201281754411.html)[⁠⁣ ⁠⁣](https://wap.cnki.net/touch/web/Journal/Article/YQTB200504014.html)[15](https://wap.cnki.net/touch/web/Journal/Article/YQTB200504014.html) 。

总之，PAM降解后的产物及其对环境、水质和微生物的影响需要引起重视，并采取有效措施减少其负面影响[⁠⁣ ⁠⁣](https://m.renrendoc.com/paper/373782432.html)[2](https://m.renrendoc.com/paper/373782432.html)[⁠⁣ ⁠⁣](https://jz.docin.com/touch_new/preview_new.do?id=4816937762)[6](https://jz.docin.com/touch_new/preview_new.do?id=4816937762) 。
